Even if you were not employed at will, violating your employer's policy would be sufficient "just cause" grounds for termination or discipline.(However, if you live in a state with a law restricting an employer's ability to fire you for "lawful conduct outside of work," that law might offer some protection.
If your company has such a policy, it is probably best to comply with the policy and disclose the relationship, especially if your relationship has reached a point where other coworkers are likely to find out about it.Also, you should never conduct any business related to your second job while working for the first employer, which includes phone calls, e-mails, and use of your primary employer's supplies or business contacts.Some companies concerned about sexual harassment have instituted strict "anti-nepotism" or dating policies which seek to prevent workers from dating certain or all coworkers.As long as the conduct does not present a conflict with the employer’s business, the activity should be allowed.However, whether blogging falls under the list of protected activities has yielded varying results in case law. A new trend is increasingly taking hold, where companies looking to reduce their health care costs have established not just a "no smoking" policy, but a "no smokers" policy.And if you use your blog to communicate with your coworkers for the purpose of forming a union or otherwise banding together to oppose bad working conditions, you may be protected by labor laws which allow you to engage in concerted activity for "mutual aid and protection." See our site's retaliation for union activity page for more information.The protections listed above are fairly limited, so if you are concerned that your employer will retaliate against you for what you're saying, or you would just prefer to keep it private, the safest bet is to blog anonymously or to restrict access to your blog.Most of the companies implementing anti-smoking policies are giving their employees time to quit smoking, and are supporting their efforts by sponsoring programs and paying for aids to quit smoking, such as medication, nicotine gum, and patches.If you value your job and truly want to quit smoking, you may want to take advantage of these additional incentives, or you may want to look for a new job without such restrictive policies.While generally these policies are designed to prevent you from dating someone in your chain-of-command, be sure that you do not violate your company's policy, which may be more strict than the most common policies.Some companies now ask that you notify the company before dating a coworker, and may require that you sign a "relationship contract," indicating that the relationship is voluntary and consensual.
