We're a team of three software developers trying to deliver a product with a lot of features and bug fixes in a little amount of time. Basically our boss decided it would be great for us all to fly to this location and sit in our hotel doing 16+ hours of development while he gets more features from the customer. This will be a four day period of work, but he's willing to compensate with days off in the following week.
I'm totally against doing this because of (1) the location I'm placed in with no ergonomic desks/tables nor access to a car or going home to relieve stress (2) 16+ hours a day will not get quality work out of me, especially four days worth of it. (3) He treats these trips as a school field trip, where we must all be together in a room at all times. Which means he'll be up my ass with new bugs and features, therefore causing more stress to the situation.
I'd be more likely to work the additional hours + stress in an environment that I know, and the ability to escape when I need breaks. However, he refused alternatively allowing us to use Skype and avoiding wasting money on the trip altogether.
This plan seems to have huge potential for burnout and sounds like a complete nightmare to me. Is it reasonable to push back against this? How can I effectively do so when the boss has already shot down my alternative suggestion? Is the location enough to justify saying no to the trip?
