It depends on why your boss wants you to do it - and why you're reluctant. Generally, managers shouldn't be forced into telecommuting any more than employees should. But sometimes higher-level managers are anxious to give the concept a try, or they have reasons for trying it that have not been discussed.

The best solution is to handle it the same way you'd handle any other difference with your boss: try to get into a discussion about why telecommuting is being suggested, how the boss thinks it might work, and what your own concerns about it are. Recognize that your boss might have some good reasons that could change your mind, and maybe you have some reasons why the boss should back off. Sometimes, however, the fact is that you're going to have to give it a try just because the boss wants you to. In that case, do your best to give it a fair try with the best chances for success - you might be pleasantly surprised how well it works out.
