The number of employees supervised can be calculated by multiplying the number of employees by the frequency for each case and then summing them up.

1*10 + 2*4 + 3*16 + 4*8 + 5*2 = 10 + 8 + 48 + 32 + 10 = 108

Therefore, the total number of employees supervised by those surveyed is 108.

Thus the answer is 108.
