Unable to Update both Title and Salary Tables same time

I have 3 Models in My Laravel App like Employee , Salary and Title. Employee Model one to Many Relationship with both Salary and Title Models. Now I need update data using EmployeeController updateEmployee function EmployeeController

public function updateEmployee(Request $request, $id) {
        $employee = Employee::find($id);
        $title = $employee->titles()->update($request->all());
        $salary = $employee->salaries()->update($request->all());
        if(is_null($employee)) {
            return response()->json(['message' => 'Employee not found'], 404);
        }
        $employee->update($request->all());
       
        return response($employee, 200);
        
    }

and my api route is following

Route::put('updateEmployee/{id}','App\Http\Controllers\EmployeeController@updateEmployee');

Employee Model

public function titles(): HasMany
    {
        return $this->hasMany(Title::class, 'emp_no');
    }

    public function salaries(): HasMany
    {
        return $this->hasMany(Salary::class, 'emp_no');
    }
}

Salary Model

public function employee(): BelongsTo
    {
        return $this->belongsTo(Employee::class, 'emp_no');
    }

Title Model

public function employee(): BelongsTo
    {
        return $this->belongsTo(Employee::class, 'emp_no');
    }

I can update Title or Salary Tables separately. but when I set both same time like

 $title = $employee->titles()->update($request->all());
  $salary = $employee->salaries()->update($request->all());

it is encounting following error Illuminate\Database\QueryException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'salary' in 'field list' (SQL: update titlessettitle= engineer,salary= 58000 wheretitles.emp_no= 2 andtitles.emp_no is not null) in file F:\2023\code\2023\api\vendor\laravel\framework\src\Illuminate\Database\Connection.php on line 760
