Having added a few work accounts to my phone over the years, the verbiage that the phone gives you is at least very specific (at least on Android) as to what power the employer has with your phone. At one point, a prior employer tried to require device management to sign into their GSuite email, and I got a prompt saying that it was required and that they could wipe my phone at will. I then removed that account from my phone and told my employer why. They backed off of that policy and later set up one less broad (i.e. they could wipe the account, but not the entire phone). Nowadays most setups allow employers to wipe the work profile but not the whole phone (and again, this is explicitly stated to the user upon adding the profile). Disclaimer: Now a Googler, opinions are my own.
