Talk to your supervisor or person in charge of the dispatching agency.
On top of that, let's ask the dispatcher to make a complaint or change the dispatch destination, or ask them to respond.
A temporary job is to do contract work.
However, in such an environment, you can't work under a contract, right?
Therefore, I think it is necessary to demand environmental improvements or cancel the contract.
Even if you make a complaint to the dispatcher, they haven't heard it, so let's talk to your supervisor or person in charge at the dispatching site.
Don't burden yourself with everything.
Please reduce your mental stress even a little by increasing your break time and number of breaks while working.
If an employee at the temporary location tells them that they are taking too many breaks, the person next to them will cause stress, so they will properly say that they need a lot of breaks.
The dispatch contract will eventually come to an end.
I'm not going to meet my employees forever.
So, there's no need to be a nice and comfortable kid.
